Conception can occur mere hours after male ejaculation, so the use of a coil or pill after the fact can indeed be argued to be
abortion. Tho' science is not quite certain, it's felt that most conceptions occur a few days after sex. So those would technically not be abortions but rather
birth-control,
protection or
contraception.
As there's no way of knowing exactly when conception occured after unprotected sex, Kavanaugh is erring on the side of his conservative religious caution.
By the way I'm not agreeing with his possible implication that using these controls mere hours or days after sex should be seen as a morally negative thing. But he does have a point, however skinny.
The celebrated National Geographic documentary
Life Before Birth - In the Womb muses over when life begins once the sperm reaches the egg. If it begins at conception, and conception can occur before an IUD or somesuch is used, then yes you can technically call it an
abortion, so those methods or drugs can thus
technically be called “abortion-inducing drugs”.
